Top notch speakers with their own sub


I have a pair of Infinity Prelude MTS complete with subs and towers. They serve me very well, don't require too much power because they have their own powered subs. The multiple components for upper base and mid range do have their advantage, giving a rather complete sound projection. This pair of Class A speakers certain have lived up to their pedigree, but the technology is about 10 years old. What would recommend for the current technology? I am looking for a pair of full size speakers that have their own powered sub.

I read this thread with dropped jaw as no one has yet mentioned the finest speakers of this description. They being the time and phase coherent Vandersteen 5A.

MBL 116 and MBL 111

Avantgarde Duo's

YG Acoustics Kipod

Martin Logan Summit X

Someone up there mentioned "Vandy V".

In the Vandersteen line the top 4 -- Quatro, Quatro Wood, 5A, and the new 7 -- have integrated powered subwoofers with 11-band EQ and contour controls.

I'm more suprised no one mentioned the Definitive Technology Mythos STS and ST speakers. No bass EQ, though.
I listened to the Vandersteen/Ayre combination at a show and did enjoy the relaxed presentation. However this was a show with people constantly came by. So it wouldn't be fair if I conclude that Vandersteen 5A is about a trade off to Prelude MTS. Does anybody have studio comparison between Vandy 5A and Prelude MTS or Watt/Puppy 8?

>The Deqx idea I mentioned in my previous post is simply a "brute force" EQ solution. It allows the peaks and nulls to develop and beats them into submission with EQ. Audyssey and Velodyne (among others) also make EQ products for this purpose.

Nulls can't be fixed with equalization. With a 10dB NULL you need 10X the power or 3X the displacement you have at other frequencies. With 20dB it's 100X or 9X.

If you need 100W for sufficient bass head-room and aren't excursion limited, you'll need at least 2000W to overcome a 10dB null due to thermal compression. If you are excursion limited and are stacking woofers in the same location you'll need to triple their count.

Listener and/or speaker movement are the only reasonable solutions for nulls. I had to move my chair six inches to get decent bass in my current living room.
